I was experimenting with play and pause when a video is within the viewport... when I was searching around I found the following code.. which unfortunately didn\'t work:
I agree with what you said in your question: users might not like it, especially if they're on mobile and you're sucking all their data plan. Anyway, here's how to check if an element is in the viewport: http://jsfiddle.net/pwhjk232/
$(document).ready(function() {
var inner = $(".inner");
var elementPosTop = inner.position().top;
var viewportHeight = $(window).height();
$(window).on('scroll', function() {
var scrollPos = $(window).scrollTop();
var elementFromTop = elementPosTop - scrollPos;
if (elementFromTop > 0 && elementFromTop < elementPosTop + viewportHeight) {
inner.addClass("active");
} else {
inner.removeClass("active");
}
});
})
Instead of using addClass you could use .get(0).play() and .get(0).pause() as suggested by Vohuman
